It seems zend.exception_string_param_max_len is not recognized

[PanosPetrou]

In my environment zend.exception_string_param_max_len is set to 0 in my php.ini.

I get frequent php warnings such as:

PHP Warning:  [snuffleupagus][0.0.0.0][ini_protection][log] Cannot hook INI var `zend.exception_string_param_max_len` Maybe a typo or the PHP extension providing this var is not loaded yet. in Unknown on line 0

You might want to comment the sp.ini.key("zend.exception_string_param_max_len").ro(); line in the config/ini_protection.rules, since it sets this configuration variable as read-only.
